DiaMune feed additive combines the unique bioactive compounds found in XPC® with organic selenium yeast cream in a convenient premix for all classes of ruminants, swine, and poultry.

DiaMune postbiotic is not a single compound, but rather a microbial fermentate composed of hundreds of bioactive compounds plus organic selenium that work synergistically with the biology of the animal to support health and performance.

DiaMune postbiotic is produced using Diamond V’s proprietary Saccharomyces cerevisiae fermentation technology platform and blending with organic selenium yeast cream.

Research shows the bioactive compounds in DiaMune feed additive work naturally with the biology of the animal to help maintain immune strength, support digestive tissue integrity, and promote a healthy microbial balance

In addition, the organic selenium yeast cream in DiaMune postbiotic helps maintain the proper selenium balance in the animal. Selenium deficiencies can result in many challenges to the animal, including immune health, reproductive and post-partum health, production performance, and others.

Yes. The bioactive compounds and the organic selenium yeast cream in DiaMune fermentate have a two-year shelf life. The product is very stable through processing conditions normally found in feed and pet food manufacturing.
